TDR function, John Larkin may like it!
Will see where it goes...
Have to read up on those sites...

Interesting, thank you
For about 10.7 GHz to 12.75 GHz and about I use my satellite LNBs, output to SDR_RTL spectrum analyzer.
LNBs make great downconverters...

I'm sitting here looking at an instrument that blows my mind. It
is a miniature had held spectrum analyser that sweeps from 100
KHz to 12 Ghz. 12 Ghz! I'm looking at the WiFi channel at 2.54
GHz with a waterfall display. Sure, it doesn't have the dynamic
range of a R&S, but it doesn't cost as much either. It is good
enough for my purposes.
I have recently collected a respectable group of test equipment
for not much dinero that anyone can enjoy. All prices are in

For those interested in wideband reception, there are an
enormous amount of articles on discone antennas that can go from
25MHz to 2GHz. Here is one:

The Nanovna might be useful to tune these antennas.
